Case Study: C4 to C6 Anterior Cervical Discectomy

and Insertion of Intervertebral body biomechanical

devices from C4 to C6

A pleasant patient who was involved in a car crash and subsequently developed neck pain. They had lots of conservative treatments, but ultimately failed, and developed myelopathy with correlated imaging findings from C4 to C6. Therefore, we offered surgery. The patient gave informed consent, understanding all of the risks, benefits, and alternatives to surgery.

Mild degenerative changes C4-C5 and C5-C6

The patient was identified in the Preoperative Holding Area by two separate patient identifiers and then brought back to the Operating Room where they were induced under general anesthesia and intubated without incident.

Neuromonitoring electrodes were attached and tested. The patient was placed supine on to the Operating Room table with their head in a gel doughnut and a small interscapular bump placed to position the neck in a natural lordotic position.

We localized our incision using a radiopaque marker and traced the incision with an indelible marker from the midline of the trachea to the medial border of the sternocleidomastoid muscle on the patient’s right side. We then prepped and draped the neck in the usual sterile fashion, dosed IV antibiotics, and completed a call to order.

A #15 blade was used to incise the skin along the natural skin crease and thereafter reverse Metzenbaum technique was used to create a subcutaneous dissection plane. We then undermined the platysma muscle and cut it sharply using bipolar cautery to control bleeding.

Subplatysmal dissection was carried out with mosquito hemostats and reverse Metzenbaum technique. We followed the fascial plane on the medial border of the sternocleidomastoid muscle down to the fascia anterior to the spine, carefully retracted the esophagus and carotid artery out of view. We localized our level of operation using fluoroscopy.

We used handheld retractors to hold the skin and muscle edges apart and deflated the endotracheal cuff to just before a cuff leak. Undermining the longissimus muscle with Bovie cautery and freeing up the disc spaces from overlying tissues, we were then able to apply our self-retaining retractor set and completed our exposure of the disc spaces from C4 to C6.

There was significant osteophytic overgrowth and we removed this bone and flattened the anterior vertebral bodies using Leksell Rongeurs and the drill. We morselized and saved this bone for use later in the case.

At this point, we placed Caspar pins into the C5 and C6 vertebral bodies and applied gentle distraction. Using a combination of curettes, Kerrisons, rongeurs and pituitary rongeurs, we started our discectomy and applied gentle distraction as we continued our discectomy down to the posterior longitudinal ligament.

The disc was extremely degenerated at this level and we reached the posterior longitudinal ligament and undermined it and resected it using 2 mm and 3 mm Kerrison punches.

Posterior osteophytes were then removed with a drill and Kerrison punches then we created wide foraminotomies bilaterally. We followed the nerve roots out through the neural foramen using the blunt nerve hook freeing them from all compressive elements and mobilizing them.

Epidural bleeding was controlled easily with Surgiflo and gentle cotton tamponade. We then trial-sized our implant and obtained x-rays. We filled our implant with morselized allograft and morselized autograft.

We inserted it carefully under direct visualization and used x-rays to ensure appropriate placement. We removed the inserter and washed out the wound. We thereafter removed the Caspar pin from the C6 vertebral body and covered the hole with bone wax.

We transferred our attention to the C4 C5 disc space and frame-shifted our retractors cephalad. We inserted a Caspar pin into the C4 vertebral body, applied gentle distraction, and repeated the process here for discectomy and arthrodesis. Using a combination of curettes, Kerrisons, rongeurs and pituitary rongeurs, we started our discectomy and applied careful distraction as we continued our discectomy down to the posterior longitudinal ligament.

The disc was extremely degenerated at this level. We reached the posterior longitudinal ligament and undermined it and resected it using 2 mm and 3 mm Kerrison punches.

Posterior osteophytes were then removed with a drill and Kerrison punches and we created wide foraminotomies bilaterally and followed the nerve roots out through the neural foramen using the blunt nerve hook freeing them from all compressive elements and mobilizing them. Epidural bleeding was controlled easily with Surgiflo and gentle cotton tamponade.

We squared out the disc space with the high-speed drill and prepared the disc space for arthrodesis. We then trial-sized our implant and obtained x-rays. We filled our implant with a morselized allograft and a morselized autograft.

We inserted it carefully under direct visualization and used x-rays to ensure appropriate placement. We then removed the inserter and washed out the wound. We thereafter removed the Caspar pin from the C4 and C5 vertebral bodies and covered the holes with bone wax.

At this point we measured out our anterior plate, placed it over our levels of interest, and pinned it into place. We obtained x-rays, and then removed the plate and applied additional curvature to the plate to seat it appropriately against the anterior border of the vertebral bodies. We then replaced the plate and applied the screws as listed above. We locked all the screws in place and obtained final AP and lateral x-rays.

We then washed out the wound copiously with Bacitracin irrigation and used bipolar cautery to achieve meticulous hemostasis. We applied steroid paste to the retroesophageal space and closed the platysma muscle with a running #3-0 Vicryl stitch. The platysma was reapproximated using 3-0 running Vicryl.

The deep dermal layer was closed with inverted interrupted #3-0 Vicryl sutures and the skin was closed with a #5-0 running subcuticular Monocryl stitch. The incision was dressed with Steri-Strips and the patient was placed in a cervical collar prior to being transferred off of the Operating Room table extubated.

All counts were correct at the end of the case x2 and I was scrubbed for all portions of the case. There were no changes in neuromonitoring throughout the case. The patient was extubated in the operating room.

The patient initially followed up in two weeks after the surgery and then continued to follow up as an outpatient every 4, 6, 8 weeks. In their last office visit the patient stated they were well, able to do their usual activities and myelopathy had been resolved.

I had such a wonderful experience with Complete Orthopedics in Stony Brook. Not only did Dr. Kuo fix my broken wrist with such kindness and care, but the office staff, including Billing, Reception and the X-Ray Technician, was always so helpful, going out of their way to ensure that each patient felt welcome, answering any questions with a smile, and ensuring any issues with insurance/billing were handled with the utmost professionalism. I highly recommend their practice!

I'm very happy St. Catherine's sent me to this office for treatment after I broke my collar bone! Unfortunately the break was too severe to repair on its own and I had to have it rebuilt a week after the injury. Dr. Vaksha did a great job fixing it. I'm three months out, and I have full use of the arm and shoulder. The whole office staff is very professional, accommodating, and welcoming. I hope to not need orthopedic services again, but Dr. Vaksha will be my number one choice if I or anyone in family suffers such am injury.

Scheduling my appointment was quick and easy. The staff was super friendly and down to earth. I was seen on time. The appropriate test, “x-rays” were taken before the conversation with doctor, something I really liked, test for analysis and conversation was done upfront. Dr. V had a great personality and was no BS, straight forward diagnosis and a play on next steps. I am happy I found them and would refer them to friends and family.

After suffering from a severe ankle injury Dr. V was able to help me heal and return back to work completely to a job where I stand for 12 hours a day. The office is very clean and I appreciated the reminders of my appointments via phone call and through text. The patient portal made it easy for me to access all my documents including work notes. The office staff is wonderful and Rebecca was able to schedule me with a busy schedule and awesome at answering all of my questions including referring me to a great physical therapy office. I highly recommend this office to anyone who’s looking for knowledgeable and kind orthopedic office.

I was rear ended in an auto accident , Dr Vashka was recommended by a friend of mine .I was experiencing Back , neck , and shoulder pain . After a thorough examination and given exercises to do at home , I am feeling much better , and I ended up avoiding surgery . The staff at Complete Ortho is extremely attentive and show great care when making an appointment and are very friendly and i never waited more than 5 minutes for my appointment . So I would strongly recommend Complete Orthopedics for any aches and pains that one might be experiencing.....

It was the afternoon of Friday Sept. 24. We were in Pt. Jefferson and my wife, Mary Ann, broke her hip. We went to Mather Hospital and it was determined that she would have to have an operation to have it repaired. This would be her third time under the knife in the past year. It just so happened that we were very fortunate enough to have Dr. Karkare, who was on standby, perform the surgery. He put in a rod and two screws in her hip. She spent a few days in the hospital and then went to Gurwin rehabilitee for another few weeks.It has now been almost six weeks and we both worked the election the other day. If it wasn’t for Dr. Karkare’s expertise she never would have been able to work. She is able to walk with a walker and is doing physical therapy three times a week.We can not thank the doctor enough for the compassion and dedication that he puts into his work. It allows Mary Ann do the things that she likes to do, even on a limited basis for a while. I know that with her will, perseverance and the great work that the surgeon performed she will be back on her feet in no time.Sincerely:John V. PlumpEast Northport, NY 11731

In the year of 2018 I was referred to Dr. Karkare because I was experiencing severe knee joint pain. After exhausting physical therapy and trying to labor through the pain, I had to make a quality of life decision. Total knee replacement was the only viable option. Dr. Karkare made my decision easy as he walked me through the whole process from surgery to recovery.On 12/13/19 ( Friday the 13th) I enter Lenox Hill Hospital in great hands. From the time I entered Dr. Karkare’s office for the first time until now, his staff has been amazing. Andrea the medical coordinator walked me through all the paper work and necessary preparations for the surgery. Courtesy and kind would be an understatement. Dr. Karkare went over and beyond from the wellness checks and phone calls all to assure me that I was important to him. This was the right decision no pain and no limp. Complete Orthopedics should be your choice!

I suffered with pain in both knees for years. My orthopedic doctor kept recommending knee replacement . I fought it for years, as I was just afraid. When I had no choice and could barely walk , it was recommended I see Dr. Karkare. We set up a consultation and my wife and I left his office feeling totally confident and comfortable with moving ahead with the surgery. He explained everything to us, and the office staff set everything up for us and made the process easy. So about one month after our initial meeting I had the first knee done. I was up walking mere hours after the surgery, and on the workout machines the next morning. I went home two days after the surgery, and yes walked my daughter down the aisle at her wedding only one week after the surgery without even a cane! Three months later I had the other knee done and went home the very next day. Dr. Karkare put my fears to rest . I would highly recommend him. His expertise gave me my life back. Thank you Dr. Karkare.SincerelyVito Congro
